Has anybody actually done the rear diff swap on 400E/E420 (without ASR)? Which diff was used? Out of which model? What was the cost? What were the results? And I know I've searched the issue and there was a long discussion re 2.82's and 3.xx's out of 300SL??? And I'll be damned if I can now find it using the search feature. Also, my E420 does NOT have ASR, so I guess I'm screwed on the 500E diff. Any suggestions? Thanks, all. --Mitch
